Deadmau5 Pranks Skrillex by Sharing His Phone Number at Grammys

At last night's Grammy Awards (February 12), deadmau5 showed up wearing his signature giant mouse head, but the Canadian dance guru also known as Joel Zimmerman was wearing another, even more hilarious article of clothing: a T-shirt emblazoned with Skrillex's personal phone number.

Deadmau5, who was up against Skrillex in several categories (Best Dance Recording, Best Dance/Electronica Album, Best Remixed Recording Non-Classical), pranked the rising dubstep star by wearing a shirt that read "(626) 319-1039 u mad bro?"
